How do I stop inadvertently spamming the council?

[Tygertiger]

I’ve sent the same email to a department in the council three times. However, I only intended to send it once, and when I did, they dealt with it! Since then, my phone has sent the same email two more times - a week or so apart, at random times. I only ever sent the email from my phone and it’s now doing it itself. I have emailed them to apologise and ask them to ignore it but what on earth do I do to stop it being sent again? It’s coming from my Hotmail account which is linked to the email app on my phone (iPhone). Any ideas?

This is what AI suggests:

Restart Your iPhone
A simple reboot can clear temporary glitches that cause repeated sending.

Remove and Re-add Your Hotmail Account
Go to Settings > Mail > Accounts, tap your Hotmail account, and choose Delete Account.
Then re-add it using Add Account > Outlook.com — this ensures proper syncing.
This fix is confirmed by users in the Microsoft Community and Apple Support.

Avoid Adding Hotmail as “Other”
If you added Hotmail manually under “Other,” it may not sync correctly.
Instead, use the Outlook.com option when adding the account — this resolved the issue for many users.

Check for Outbox Messages
Open the Mail app and check your Outbox folder.
Delete any stuck messages that may be looping.

Reset Network Settings
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
This can fix connectivity issues that cause repeated sending.

Update iOS
Make sure your iPhone is running the latest version of iOS.
Updates often fix bugs that cause duplicate messaging.
